2017-10-16 12:13 CEST policyd-weight.service has been manually restarted.

policyd-weight.service is automatically generated by systemd-sysv-generator and use /etc/init.d/policyd-weight. /etc/init.d/policyd-weight stop calls start-stop-daemon without --retry, that's why /etc/init.d/policyd-weight start could be called while policyd-weight hasn't been stopped resulting in Address already in use.

Remedies:

setup policyd-weight.service without using /etc/init.d/policyd-weight
add restart=yes in policyd-weight.service

I think EnvironmentFile should be /etc/default/policyd-weight and the start action should keep $DAEMON_OPTS to follow the package's behavior (so that we can then suggest it in a Debian BR).

Would it be possible to do a -k stop; the manpage does not seem to say it would be wrong, but I guess we would have to try to be sure.

As for the security restrictions, that's a very good idea because this daemon is not supposed to need anything else. So if it works well then GoGoGo.

The rest is fine :-).

Indeed.
